I would get one of those "oil radiator" style electric heaters from local store and put it in the trunk. and take the carpet off the fuel tank in there. set it on low. should keep your fuel tank warm, and also help warm up the car interior too! DO NOT USE the TOASTER element style heater in your tank... bad idea.
I would also go under the car, and run a water line heat tape along the fuel lines and cover them with foam insulation well attached to the car.
this should cover it for you to start the car and keep it running.

the last time this happened, not that long ago actually, I found that methyl hydrate worked fairly well. I dumped 2 litres in, it boosted power and I'm gonna guess some sort of capillary action thru the fuel lines. and it's only $1.99 a gallon!

When it is that cold out, without fuel line heaters you will have some real issues once you get on the road. If the fuel you have will gel at the ambient temps, the lines under the car will quickly cool to approximately ambient just from air flow under the car. Been there and it is easy to get stuck in the boonies. Best bet is to add an anti-gelling additive, which according to MB can be gasoline up to 35% in an emergency, and then get it running so you have an appropriate mix in the fuel lines. Jim

PanzerSD, your best bet is to get the car inside and thaw it out. If you absolutely can't (I'll bet you can figure out a way), then you'll have to blow the fuel line backwards from the fuel pump to the tank and then think about getting the fuel out of the tank and dewatering it. Bad luck sometimes happens and it was your day to buy bad fuel. Then, when you've got known good fuel and have the system reprimed (use a hair dryer on the injector lines and change the secondary filter) give it a try.

I like my tank-style coolant heater. The cat's meow if there's room.

I've also pulled pickups and trucks in and used a "knipco" heater pointed at the radiator, with cardboard blocking off the sides and rear and the hood cracked a bit, so the hot air blows through the radiator and up. This in an unheated garage after blowing the fuel lines back.

I bet you're thankful for global warming. Imagine how tough it would be to run that diesel without it!
